Title: Manufacture of metallic hollow spherical body
Inventor: YAMAZAKI KOTARO
IPC: A44C27/00
Filed: 1991-11-19
Abstract: PURPOSE: To easily form a seamless hollow sphere with a uniform thickness by forming a cylindrical body with a semi-spherical bottom from a metallic sheet, drawing the opening edge inward to form a half-finished hollow spherical body and pressing it into a spherical shape while rotating. CONSTITUTION: A cylindrical body with a roughly semi-spherical bottom is formed from a metallic sheet and, by drawing the opening edge of this cylindrical body inward to gradually form a small diameter, a half-finished hollow spherical body 5 is formed. This semi-finished hollow spherical body 5 is arranged between the forming grooves 14, 15 of a roll forming die 11, and either the upper die 11a or the lower die 11b is fixed while the other is rotatably driven. The small opening 4a of the semi-finished hollow spherical body 5 is gradually reduced between the forming groves 14, 15, and finally made to disappear; thus, a metallic hollow spherical body without the opening is formed.

Abstract: PURPOSE:To preclude the blackening of a transparent electrode, the discoloration of dichroic pigment, the deterioration of the ferroelectric liquid crystal and to improve the contrast even when the liquid crystal is driven for a long time by setting the mean voltage level of pulses applied to the ferroelectric liquid crystal to zero. CONSTITUTION:A response signal is supplied and then DC pulse P1 with a voltage V are applied to the ferroelectrtic liquid crystal, which enters a saturated response state and then are applied with pulses P2 generated by superimposing high frequency AC pulses F on DC pulses having symmetry with the DC pulses P1 and the opposite polarity. A reverse response signal, on the other hand, is supplied to apply DC pulses P3 having a voltage -V to the ferroelectric liquid crystal, which enters a reverse saturated response state; and then pulses P4 generated by superimposing the high frequency AC pulses F on the DC pulses which are symmetrical with the DC pulses and have the opposite polarity are applied. Therefore, the mean voltage levels of the DC pulses P1 and pulses P2, and DC pulses P3 and pulses P4 are both zero. Consequently, even when the liquid crystal is driven for a long time, the blackening of the transparent electrode, the discoloration of the dichroic picture element, and the deterioration of the liquid crystal are not caused and the high contrast is obtained.

Title: Angular acceleration detector
Inventor: MARUYAMA TOSHIYOSHI
IPC: G01P15/03
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To obtain an angular acceleration detector comprising first and second slit groups being displaced relatively depending on the angular acceleration in which a highly accurate detection can be ensured regardless' of fluctuation in the output caused by the pitch error of the slit. SOLUTION: The angular acceleration detector 10 comprises first and second slit groups 16, 17 being displaced relatively depending on an angular acceleration generated on a rotary shaft 13. Absolute angle of a first disc 14, on which the first slit group 16 is formed, is detected by an absolute sensor 30. Fluctuation of output caused by the pitch error of the slit groups is stored in a ROM 50 in relation to the absolute angular position of the first disc 14. An output compensation circuit 40 reads out a fluctuation of output corresponding to the absolute angular position of the first disc 14 and performs a operation for removing fluctuation components contained in the detected value of angular acceleration. A resulting signal is employed as an angular acceleration detection signal. According to the arrangement, a high accurate detection of angular acceleration can be ensured by removing fluctuation in the output caused by the pitch error of the slit.

Filed: 1994-12-08
Abstract: PURPOSE: To enable detecting a lag in ignition by using an air-pressure sensor relating to a device having the air-pressure sensor in an air-feeding passageway. CONSTITUTION: The feed pressure P of the air for combustion in an air passageway is monitored, the time ΔT taken for the feed pressure P, after an ignition signal is given, to reach a prescribed pressure P0 is wasted, and if the time ΔT is greater than a preliminarily set reference T0, the combustion device is judged to be in disorder. As a result, anything the matter therewith, such as fouling of the burner with age and inappropriateness in the control of the combustion, can surely be detected and can be attended to promptly by cleaning of the burner and correcting the control of the combustion. Furthermore changes with age can be monitored so that the device can be prevented from seriously malfunctioning such as a failure to ignite.

Title: Opening and closing noise elimination device for rear cover
Inventor: KATOU RIYUUKOU
IPC: G03B17/02
Filed: 1993-12-27
Abstract: PURPOSE:To prevent the resonance noise of a spring generated when the spring contracts after it elongates once because a pawl gets over an opening and closing knob at a closing time by providing the knob for opening and closing a rear cover with a resonance preventing member. CONSTITUTION:This device is provided with the rear cover of a camera, the opening and closing knob 2 of the cover 1, the spring for returning 3 of the knob 2 and a member for eliminating the noise of the spring added on the knob 2. When the cover ] is opened, the engagement of the cover 1 and the pawl is released by actuating the knob 2. Then, the cover 1 is opened. When the cover 1 is closed, the pawl of the knob 2 is depressed by the pawl of the cover 1 by closing the cover 1 as it is. Then, the cover 1 is closed. Since the knob 2 is lowered once at this time, the spring 3 elongates. When the pawl is engaged, the spring 3 suddenly contracts. At this time, the resonance noise of the spring 3 is conventionally generated. However, the resonance noise is prevented from being generated by the noise elimination member 4. Besides, the catching noise of the spring 3 is also prevented from being generated when it elongates.

Inventor: KATAYAMA MASAHIRO
IPC: B60C11/11
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire that has improved the travel performance and partial wearing resistance on the ice road. SOLUTION: In a block 18 in which a plurality of sipings 20 are formed, a recessed section 22 is formed in every other small blocks 18A in an R arrow mark side, and a recessed section 22 is formed in every small blocks 18A, on which a recessed section 22 is not formed, in an L arrow mark side. When a block 18 contacts the ground, walls of sipings 20 contact each other, restraining the deformation of small blocks 18A due to their inclination. Since force (moment) f2 is generated near the recessed section 22 of each small block 18A and works on the contact face of the siping 20, the deformation of each small block 18A due to inclination is further restrained, improving the travel performance and partial wearing resistance of a pneumatic tire is further improved.
